Bistability and boundary crisis in a semiconductor laser with phase-conjugate feedback [PDF]
We present a detailed study of a route to chaos via quasiperiodicity on a torus in a semiconductor laser with phase-conjugate feedback. Highlighting the use of new tools that go far beyond mere simulation, we compute bifurcation diagrams and unstable ...

Thiol-Amine Processed PbS Thin Films for Enhanced Near-Infrared Photodetection
Developing reliable processing routes for semiconductor thin films is essential for advancing photodetection technologies. The amine-thiol solvent system, in comparison with other liquid-phase synthesis methods, does not necessitate stepwise ion-exchange

Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

Pure frequency oscillations of semiconductor lasers with filtered optical feedback [PDF]
A semiconductor laser subject to delayed filtered optical feedback can show pure frequency oscillations with a period of the order to the delay time, while the power remains practically constant.

Generating of Chaotic Signals by using Semiconductor Laser with Optical Feedback [PDF]
This paper addresses theoretically generating the chaotic signals by using semiconductor laser diode of 1550 nm with optical feedback. The performance of a semiconductor laser subjected to a delay optical feedback was investigated using rate equations ...

In situ Auger Electron Spectroscopy resolves oxidation states with high fidelity during the pulsed laser deposition of multivalent perovskite manganate and vanadate heterostructures. The chemical‐state signature is carried by the valence‐electron population of the transition‐metal cation, read out through the relative intensities of Auger fine ...
